Privacy

Available does not collect anything about you.

There is no account to make and no server of ours to sign in to. Your calendar is never sent anywhere. The one thing the app sends over the internet is your settings, to your own iCloud, as described below, and you can switch that off. Without a connection the app works as before.

Your calendar

The app reads the calendars on your phone to work out which days you are free. It reads them while it is open, holds what it finds in memory, and forgets it when it closes. Your appointments are not copied into the app's own storage, and none of it is sent anywhere.

The app only reads. It never creates, changes or deletes an appointment.

iOS does not offer a read-only calendar permission. The choices Apple gives an app are "add to your calendar" or "full access", and full access is the only one that allows reading. So the app asks for full access and then only reads. You can check this for yourself: the source code is available on request.

One exception, and it is worth being precise about

If you tell the app that an entry should always leave you available, or always make you unavailable, it has to recognise that entry next time, and the only thing an entry reliably offers is its title.

The title is not what gets stored. What gets stored is a fingerprint of it: the title run through a one-way function, keyed by a random number held in your device's Keychain. It matches the same entry every time and cannot be turned back into the title. Someone holding the file, even with a list of every matter you have ever been in, could not work out which is which without that key.

The Rules screen still shows you the real names. It gets them from the calendars already open in front of it, not from the file.

Marking a single day, or one occurrence of an entry, stores a date and an identifier from the calendar. A line you type over a month stores what you typed, because that is your words rather than your diary's.

What else is kept, and where

The app remembers your settings: your name and letterhead, which calendars to read, your rules, and any day you have marked by hand. On each device they are kept in a file protected by the system's own encryption, which ties it to your passcode: while the device is locked the file cannot be opened at all.

So that your iPhone, iPad and Mac are set up alike, the same settings are also kept in your own iCloud, in the app's private space in your account. We cannot see it: it is stored by Apple the way the rest of your iCloud data is. The key that makes the fingerprints above travels with them in iCloud's end-to-end encrypted storage, which not even Apple can read. Your calendar entries are never part of this. You can turn it off on any device, under Sync with iCloud in Settings.

Deleting the app deletes what is on that device, except for the key your dates are sent to, which lives in your iCloud Keychain and comes back if you install the app again. "Erase all data" in Settings deletes everything, that key included, there and in iCloud; another of your devices that still syncs will put its copy back, so erase on each one.

Public holidays

If you add a public holiday calendar, the app hands the address to iOS and iOS subscribes to it, the same as if you had typed it into the Calendar app yourself. The app does not fetch it, and whoever publishes that calendar sees a request from your phone, not from us. We do not run those calendars and have nothing to do with them.

Paying

Nothing is charged while Available is a beta, so none of this happens yet.

The one-off payment is handled by Apple through the App Store, and the free fortnight is counted from the App Store's record of when your Apple Account first got the app. We never see your card, your address, or your name. Apple tells the app one thing: whether this Apple Account has paid.

Other apps

When you send your dates, iOS hands the document to whichever app you chose: Mail, Messages, or anything else. What happens to it after that is between you and that app.

The app has a part that runs inside Messages, and actions you can use in Shortcuts and with Siri. They read the same file on your phone and work out the same list, and they do not send anything anywhere either: whatever they make goes only where you put it.

This website

The website counts how many times its page is loaded, and nothing else: no cookies, no addresses, nothing about who you are.

Changes

If this page changes, the date below changes with it. Nothing is collected by us, so there is nothing to opt in or out of beyond the iCloud switch above.
